Michelle Corson, 43, of Skowhegan, Maine, was arraigned by video Monday morning in the circuit court in Brentwood. She is charged with being an accomplice to first-degree murder and conspiracy to commit murder.

Corson’s brother Aaron Desjardins has been arrested and charged with killing Warf in March by slitting her throat and severing an artery.

Firefighters found Warf’s body inside an abandoned concrete plant on Hampton Road in Exeter on the morning of March 7 after the building caught fire.

An autopsy later showed Warf had been slain. Prosecutors say Warf was forced to enter the concrete plant at gunpoint.

It was Corson who allegedly supplied the gun, a .32-caliber German Mauser pistol. She is accused of delivering the weapon to New Hampshire on March 6 after receiving a coded text message from Desjardins’ new wife, Sarah Desjardins.

Investigators say before the murder, Sarah Desjardins sent a text message to Corson asking her to bring a “roasting pan” to New Hampshire. The words were allegedly a code meaning Corson should bring a gun to the state.

In court Monday, prosecutors asked for Corson to be held without bail, citing precedent that a Superior Court judge should rule on the matter of bail. Senior Assistant Attorney General Susan Morrell said Corson faces a potential sentence of life in prison without parole if convicted on the charges.

The accomplice to first-degree murder charge alleges Corson acted with the intent to help her brother murder Warf by providing the pistol. A second charge alleges between Jan. 1 and April 1, 2013, she conspired with her brother, his wife or both to kill Warf.

Corson spoke only a few words during the hearing, indicating that she did not wish to challenge the bail order and agreeing to seek a court-appointed attorney.

She is scheduled to appear again in circuit court for a probable cause hearing at 10 a.m. May 13.
